The new C8051F41x microcontrollers integrate up to 32-KB flash memory and high-performance analog peripherals (including a SmaRTClock with failsafe recovery features) in a compact 5 × 5 mm package. The C8051F41x microcontrollers also offer a versatile voltage supply from 2 to 5.25 V with an on-chip programmable voltage regulator and up to 5-V tolerant independent I/O voltage control. The microcontrollers’ small sizes make them ideal for portable equipment, instrumentation and measurement devices, consumer medical products, and industrial meters.

The C8051F41x microcontrollers feature a high-speed, pipelined, 50-MIPS 8051 core, 16- to 32-KB flash memory, and 2 KB. They feature on-chip peripherals such as a 12-bit, 200-ksps ADC, two 12-bit DACs, a temperature sensor, a programmable voltage reference, and comparators. The on-chip voltage regulator may be used to supply power to external ICs in the system. This makes it ideal for legacy systems with high-voltage supplies, as well as new battery-powered systems that require low-voltage operation.

The C8051F41x microcontrollers feature a 2% accurate precision internal oscillator that eliminates the need for an external crystal or resonator. On-board serial communication peripherals include UART, SMBus, and SPI bus serial ports. 

The C8051F411/3 comes in a 28-pin QFN package. The C8051F410/2 comes in a 32-pin QFN.

Pricing begins at $2.56 in quantities of 10,000. The professional C8051F410DK development kit costs $99. The low-cost C8051F411EK is available for a special promotional price of $29. The reference design kit costs $49.
